Up until the end of 1994 the Patents Act allowed for extension of term. However, they were repealed when NZ moved from a 16-year to a 20-year patent term as part of its TRIPs compliance from the beginning of 1995. The TPPA will reintroduce extension of term provisions, albeit with changes to qualifying criteria. Under the TPPA patent extension of term need to be provided for delays in patent grant and delays due to obtaining regulatory approval for pharmaceuticals. In both cases, for New Zealand, it is expected that few extensions of term will be granted.
For delays in patent grant it is proposed that the extension of term will be calculated as follows and that no third party opposition to the granting of an extension of term would be allowed. The extension would be the smaller of:
For delays due to obtaining regulatory approval for pharmaceuticals there are more issues to consider. The most important issues being:
It is proposed that “unreasonable curtailment” would apply where marketing approval was obtained after grant and where the marketing approval took more than a (yet to be) specified time period (less any periods that were disregarded). The time period for biologics would be longer than for small molecule pharmaceuticals.
It is proposed that the extension of term will be the lesser of:
It is proposed that extensions of term will be limited to pharmaceutical substances so that at most only one patent can be extended for a pharmaceutical substance. Pharmaceutical products containing that pharmaceutical substance would not be eligible.
It is proposed that the extension of term would need to be applied for within a (yet to be) specified time period and that at most only one extension of term could be granted for a patent and that only the specified use of the substance would be protected. Third party opposition would apply, in the first instance before the Commissioner.
Other issues for consideration include:
